A dispenser has a barrel which is closed at one end by a base and has a plurality of apertures at the other end through which a viscous material such as a gel or lotion is dispensed. A thermoplastic seal unit closes the plurality of apertures. The seal unit is comprised of an elongated section with a plurality of projections depending from the substantially planar section, the plurality of projections aligned with and closing the plurality of apertures. The seal unit can be removable and usually not replaceable after each use of the dispenser. The thermoplastic seal unit, which preferably is a thermoplastic elastomer, is molded onto the top surface of the barrel after the barrel top surface has been formed. It is molded into the apertures to thereby close the apertures. The seal unit can have pull tabs for the easy removal of the seal unit. This seal unit provides a positive seal for the lotion or gel substance that is to be dispensed from the barrel.
A dispenser for a viscous substance comprising a barrel, a base at one end of the barrel and a plurality of apertures at the other end of said barrel, and a seal unit, said seal unit comprised of a substantially planar section with a plurality of projections depending therefrom, the plurality of projections aligned to enter into the plurality of apertures.
A method of producing a dispenser for a viscous substance comprising forming a barrel having top surface with plurality of apertures at one end, molding a thermoplastic seal unit onto said top surface area, said thermoplastic flowing into said plurality of apertures during molding to form a seal unit having a substantially planar section and a plurality of depending projections.
